Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@FabTally Safe Check honeypot risk for token 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Read-only crypto safety + "what am I signing" verification for AI agents and wallets. Fronts the FabTally Safe HTTP API (https://safe.fabtally.com).
Read-only. Never holds, moves, signs for, or broadcasts funds. No private key. Outputs are descriptive facts from public sources — not financial advice.
8 tools: 4 free teasers + 4 paid (x402, USDC on Base).
Tool | Tier | What it does |
| paid $0.02 | Multi-chain token honeypot/rug check — aggregates GoPlus + honeypot.is into a 0-100 risk score with explainable reasons. |
| paid $0.01 | "What am I signing" — decode EIP-712 / Permit / Permit2 / Seaport typed-data into plain English + risk flags (unlimited approval, malicious spender, expiry, NFT-drain). |
| paid $0.01 | Wallet approval-risk scan ranked by exposure + address-poisoning "revoke bait" detection + the revoke calldata you execute yourself. |
| paid $0.02 | Keyless pre-sign transaction analysis: eth_call revert check + static delta prediction + risk flags. |
| free | Real teaser results, no wallet. |
Chains: ethereum, base, bsc, polygon, arbitrum, optimism (honeypot.is signals on ethereum/base/bsc).

Paid tools use x402 (USDC on Base, eip155:8453). Call a paid tool with no
x_payment to receive the decoded 402 challenge (price, network, asset, payTo);
build an x402 authorization and call again with the token in x_payment. Humans
can instead prepay by card and use an X-FabTally-Key credit header on the HTTP API.
